Synchronisation
Tip!
You can use the
CAN_Synchronization
SB to synchronise the internal time base of the PLC on
receipt of the Sync telegram.
In this way, internal mathematical processes (e.g. control processes) of the PLC can be
synchronised with the mathematical processes of other bus participants that can also process the
Sync telegram.
Detailed information about the
CAN_Synchronization
can be found in chapter 6.6.
